After the first goblin invasion you already survived the goblin tinkerer NPC will spawn tied up somewhere underground, he will reforge your gear, also he sells the tinkerer station, most accessories are material for a new crafting recipe, you do the crafting for combined gear here. Check the guide or the Wiki for recipes.
Some other tips, the zoologist sells more items the more creatures you get in your beastiary, also there is a whole fishing mechanic you most likely still missed.
First you will buy a bug net from the merchant.
With a bug net you can catch all neutral critters, like bunnies, penguins, but for fishing you need bait, get some insects, worms are inside big environment generated rocks. Then you should craft a fishing rod, you can do a good enough rod with the demonite.
There is also a fishing NPC, who will give you every in-game day a new quest to solve. This NPC spawns floating on the left or right ocean surface.
